New Delhi Hit by Worst Post-Diwali Air Pollution in Years, Lahore Also Severely Affected

Following the Diwali festival in 2025, New Delhi experienced a severe spike in air pollution, with PM2.5 levels reaching hazardous concentrations many times above safe limits, leading the city to be one of the most polluted worldwide. The surge was primarily attributed to widespread use of fireworks despite Supreme Court restrictions allowing only limited use of "green crackers," with enforcement reported as lax and many residents ignoring curfews. The pollution caused significant health impacts, including increased respiratory problems and hospital visits, and disrupted daily life with schools keeping children indoors and people altering outdoor activities. Political disputes arose, with the BJP blaming stubble burning in neighboring Punjab for the pollution spike, while firecracker sales and use remained high. The pollution also crossed borders, worsening air quality in Lahore, Pakistan, prompting emergency responses including deployment of anti-smog measures. Residents and experts lament the recurring annual crisis, criticizing inadequate policy enforcement and its detrimental effects on public health and quality of life.
